摘    要:通过建立基于不规则三角形差分法的洞头岛附近海区二维潮流数学模型,在对现场实测资料验证的基础上,对北岙后涂围垦工程前后的潮流场进行了数值模拟,就北岙后涂围垦工程对周边海区的影响及围塘根部的冲刷情况进行了分析研究。分析研究结果表明,围垦工程不会对客运和货运码头及航道通航条件产生明显影响,对洞头峡的涨落潮水流、三盘大桥桥墩及其通航孔基本没有影响;单纯潮流对围塘根部冲刷的可能性很小,因此,围垦工程是可行的。

关 键 词:潮流  数学模型  数值模拟  北岙后涂  围垦工程

Abstract:A 2-D tidal flow mathematical model near Dongtou Island based on irregular triangular grid finite difference scheme is set up. On the basis of model verification against filed measured data, numerical simulations of tidal flow field before and after the reclamation project of Beiao Houtu are carried out. According to the simulation results, the effect of the reclamation project on the nearby sea area and the scouring at the foot of the reclamation wall are studied and analyzed. The study and analysis results show that the reclamation project will not cause obvious effect on the passenger wharf,freight terminal and navigational channel, causing little effect on the tidal flow, on the piers of Sanpan Bridge and on its apertures for navigation of ships, and there being little possibility for the foot of the reclamation wall to be scoured by pure tidal current. The reclamation project is feasible.
Keywords:tidal flow  mathematical model  numerical simulation  Beiao Houtu  reclamation  project
